III. Model Evolution & 교체 옵션

1. Direct predecessor replacement: 6EP1336-3BA00 (단종)

6EP1336-3BA10 is hardware-revamped version, pin-to-pin, dimension-to-dimension, function-compatible drop-in replacement, with higher efficiency and improved low-input-voltage performance.

2. New-project new-generation SITOP PSU6200 series: 6EP3336-8SB00-0AY0

메모: 6EP3336-8SB00-0AY0 supports AC-input only, no DC-input capability. Not hardware-compatible; terminal assignments differ, pay attention during selection.

1. Compatible Extension Modules (PSU8200 Modular System)

Directly compatible with SITOP modular add-ons without extra adapters:

Buffer module: 6EP1961-3BA21; DC-UPS uninterruptible module

이중화 모듈: 6EP1961-3BA00; for dual-power redundant supply

Selectivity module: 6EP1961-3BA31, multi-channel 24 V branch current-limiting protection; short-circuit on one branch will not collapse the whole 24 V busbar

1. 일반적인 애플리케이션 시나리오

PLC 제어 캐비닛, 로봇공학, 공작기계, 포트 & marine equipment, process automation. Ideal for systems requiring AC/DC dual-input (예를 들어. backup DC supply), 높은 돌입 부하, power-status feedback and remote on/off control.

1. 배선 지침
2. 입력 단자: L1, N(L2), 체육; supports single-phase AC, two-phase tap from three-phase mains, or DC input
3. 산출: Dual sets of screw terminals for +24V and 0V. Parallel both sets when output current＞15 A for current sharing and thermal prevention
4. Signal terminals: 13-14 상태 피드백; 15-16 remote on/off; both are potential-free contacts, do not connect high-voltage circuits
5. Factory default output voltage is 24 V. Fine-tune to 26-28 V for long-cable drop compensation; do not exceed withstand voltage of downstream equipment.

Mounting Instructions for 지멘스 6EP1336-3BA10 (PSU8200-20A)

1. 장착 유형

표준 장착: EN 60715 compliant DIN-rail (TS35-7.5 / TS35-15, 35 mm rail) snap-in installation

Built-in spring clip on rear side, tool-free mounting. Release lever at bottom; push lever down to remove unit from rail.

❌ Wall-mounting by direct screw fastening is NOT supported. DIN-rail mounting only.

IP20 보호 등급, 실내 캐비닛 설치 전용; not for outdoor bare-field deployment.

2. 장착 방향 (Mandatory for thermal performance & 서비스 수명)

Fan-less natural convection; orientation cannot be arbitrarily changed

1. Standard position: 수직 장착, terminals facing down (입력 & output terminals at bottom of unit), unit upright. This is the only official position for continuous full-load operation.
2. ❌ 금지: horizontal side-mount, upside-down (terminals up), tilted mounting. Non-standard orientations degrade cooling and require heavy load derating; not recommended for field deployment.
3. Thermal Clearance Requirements (비판적인)

Do not mount heat-generating components directly above the power supply. Derate load when cabinet ambient＞60 ℃.

4. 설치 & Removal Procedure
5. Hook upper latch of rear spring clip onto DIN-rail.
6. Press lower section toward rail until an audible “click” confirms clip engagement.
7. Shake gently to verify firm seating against vibration loosening.
8. 제거: Push down the black release lever at bottom, swing lower part outward, lift unit off rail.

For high-vibration environments: Fit DIN-rail end stops to prevent sliding displacement.

5. Terminal Wiring & Torque Values

Perform wiring with power disconnected.

Input L/N/PE: 0.2-4 mm² conductors, tightening torque 0.5-0.6 N·m

Output +24V /0V: Dual terminal pairs; parallel both pairs for currents＞15 A for heat mitigation

Signal terminals 13-14 (OK feedback), 15-16 (Remote on/off): 0.14-1.5 mm² fine wires, torque 0.5-0.6 N·m

6. Mounting for Parallel / Redundancy Modules

This power supply can be installed side-by-side tightly on DIN-rail with compatible SITOP extension modules (중복성, buffer, selectivity modules). No side-to-side thermal gap needed between power supply and add-on modules.

7. 장착 금지
8. Do not install unit inside enclosed bottom trunking in cabinet; blocked top/bottom clearance leads to over-temperature shutdown.
9. Forbid upside-down or horizontal installation.
10. Do not place heat-intensive devices directly above the unit.
11. Indoor cabinet-use only; avoid open-air and high-humidity unprotected environments.

6EP1336-3BA10 (PSU8200-20A) 평행한 / Redundancy Guidelines + Troubleshooting Checklist

1. Parallel Operation for Power Expansion (No Fault Isolation)

맥스. 5 identical units in parallel for automatic current sharing. Dip-switch A must be set ON to activate parallel characteristic curve.

1. Hardware prerequisites: Identical order number 6EP1336-3BA10; keep hardware revisions consistent if possible.
2. 배선 요구 사항

Connect +24 V and 0 V of each unit to common output busbar. Positive cables shall have identical length and cross-section to equalize impedance for proper current sharing.

All 0 V negative terminals must be commonly grounded; floating ground is not permitted.

Common input circuit-breaker recommended for synchronized start-stop.

No-load output voltage difference between individual units ≤50 mV (factory default meets requirement; recalibrate if potentiometers have been adjusted).

3. Dip-switch settings

A-ON: Parallel mode (for power expansion)

A-OFF: Single-unit mode (공장 기본값; do NOT leave OFF for parallel operation)

4. 한정: Direct parallel for power expansion cannot isolate faults. Short-circuit on one output will pull down the whole 24 V busbar. Not for fault-tolerant redundancy.
5. 1+1 Redundant Supply (Fault-isolated, Recommended Engineering Solution)

Two PSU8200-20A units plus Redundancy Module 6EP1961-3BA00 (PSE202U) for decoupling isolation. If one power supply fails, the second takes over the load seamlessly without 24 V bus interruption.

1. DIN-rail layout: Two power supplies + redundancy module mounted tightly adjacent; terminals all face down; no side-to-side clearance required.
2. 배선의 핵심 포인트
3. Feed two power supplies from independent input circuits for maximum redundancy reliability.
4. Connect 24 V+ output of each power supply to the two input channels of the redundancy module.
5. Reliably bond 0 V terminals of both power supplies and redundancy module for equipotential connection; this step is mandatory.
6. Route redundancy-module output to field 24 V load busbar.
7. The redundancy module provides fault relay contacts, connect to PLC digital input for redundancy-fault alarm.
8. Dip-switch setting: For redundant configuration, set dip-switch A of power supplies to OFF (single-unit mode). Do NOT activate parallel mode.

⚠️ Never implement redundancy by direct parallel without redundancy module. Internal short-circuit of one unit will crash the whole 24 V system.

III. LED Indicator Reference Table

Dip-switch B: Short-circuit response selection

B-OFF (공장 기본값): Constant-current mode, 23 A short-circuit limiting; auto-recovery after fault clears; yellow LED lit

B-ON: Latching shutdown mode; output cuts off upon short-circuit; red LED lit; power-cycle reset required

1. Troubleshooting Checklist
2. No LED indication after power-on, zero output
3. Measure input L-N voltage: AC 85-275 VAC / DC 88-350 VDC; confirm PE protective earth connection.
4. Check screw terminal torque for loose contacts; verify upstream circuit-breaker status.
5. If input voltage is normal but no LED lights: Internal input fuse failure; 하드웨어 결함, replace power supply.
6. Yellow LED steady ON, output drops to 18-20 V
7. Load current exceeds 20 A → constant-current limiting mode; measure actual total load current.
8. Partial short-circuit or cable insulation damage on output side. Disconnect all loads; check if voltage recovers to 24 V under no-load condition.
9. Excessive voltage drop caused by long-distance thin-gauge cables; use larger-size output conductors or slightly raise output voltage via potentiometer for compensation.
10. Red-LED latching shutdown on power-on, 출력 없음
11. Output-side short-circuit. Test with all loads disconnected; normal no-load behavior indicates external load short-circuit.
12. Excessive cabinet ambient temperature, insufficient top/bottom ventilation clearance triggering over-temp protection; confirm ≥50 mm top & bottom clearance.
13. Output overvoltage: Ensure potentiometer is not accidentally adjusted above 28.8 V; confirm downstream-device voltage withstand rating.
14. Reset procedure: Power-off ≥60 s then re-energize; or open Remote 15-16 for ≥5 s then close again.
15. Abnormal 24V-OK (13-14) relay contact behavior

터미널 13-14 are potential-free dry contacts, closed only when output＞20 V. 접점등급: DC30 V, 최대. 0.1 에이. For PLC digital-input signal only; do NOT drive contactor coils or high-power loads.

5. Poor current-sharing in parallel; one unit runs excessively hot
6. Dip-switch A not set to ON.
7. Large discrepancy in length / cross-section of positive output cables.
8. No-load output voltage difference＞50 mV between units; fine-tune potentiometers for matching.
9. Loose 0 V wiring leading to equipotential mismatch.
10. Remote terminals 15-16 fail on / off control

15-16 are potential-free contacts: Short-circuit = output enable; open-circuit = output disable. No external supply required.

If remote function is unused: Keep 15-16 short-circuited with factory jumper; do not remove jumper.

1. 시운전 권장 사항
2. New cabinet commissioning: Power-on without load first; confirm 24 V output and steady green OK LED; connect loads incrementally.
3. Redundancy-system commissioning: Disconnect one input source at a time; verify seamless switch-over with zero load dropout.
4. High-temperature cabinet applications: Apply load derating above 60 ℃ ambient; avoid continuous full-20-A operation.
